Shuta Aoi wanted to become a hero, but after a certain incident, he gave up that dream. One year later, that incident returns to haunt Shuta. In order to face his fears again, he needs to gather his two childhood friends together and reform the RGB. Given another chance, will Shuta be able to confront his despair?

Thanks to the KANAE system which has been in use for two months, the arrest rate has been going up. After Kunai's terrorist attack, Ran is now wanted as a material witness. Koki has been transferred to the department in SARG that operates the KANAE system. Meanwhile, Shuta has had a falling-out with Koki and Ran. His father Rui has gone to Paris to study, so he has been busy taking care of the Aoi Bakery. While he is struggling to bake the Golden Sunrise bread which is a specialty of the bakery, he receives an email from Kozue.

When the RGB trio decides to go meet Asumi, they receive a call from her. Asumi presents to them a trolley dilemma that involves herself. They must decide between revealing Asumi's existence within the KANAE system which would lead to its collapse, or to fix the bug inside Asumi which would lead to everyone being controlled by the system. The trio are unable to make a choice between the two, and decide to go meet Asumi by any means. What is the future that RGB chooses?
